Bronchodilators are medications that relax muscle bands that tighten around your airways. This opens the airway and lets more air move in and out of your lungs. That helps you breathe more easily. Bronchodilators also help remove mucus from your lungs. Open airways mean mucus can move more freely, too, and you can cough it up.
Almost all people with asthma use a bronchodilator to help open their airways.
Short-acting bronchodilators are used as a “quick relief” or “rescue inhalers”, while long-acting bronchodilators can be used every day to control asthma — along with an inhaled steroid.
